Data and Methods
Britney Spears search data is from Google searches circa 2011. A slightly modified scale was used to represent the flow diagrams to make all branches’ text legible, so the sizes don’t perfectly represent the proportion of responses. We chose to only show the top 8 permutations of each name. Phonetic data is based on the International Phonetic Alphabet via Wikipedia. You can download the data yourself here.
